IMPROVED WASHING MACHINE.

T0 ALL WHOM IT MAY CONCERN:

Be it known that I, WIIJLXAM W. COX, of Carbondale, in the county of Jackson, and State of Illinois, have invented a new and improved Washing Machine; and I do hereby declare thatnthe following is a full, clear, and exact description thereof, which will enable others skilled in the art t0 make and use the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure 1 represents a vertical longitudinal sectional view' of my improved washingmachine, the plane of section being indicated by the'line a: .'v, tig. 2..

Figure 2 is a vertical transverse sectional view of the same, the plane of section being indicated by the line yy, iig. 1. l i

Figure 3 is a detail horizontal sectional view, the plane of section being indicated by the line a' e, iig. 1.

Similar letters of reference indicate like parts.

This invention relates to an improved washing machine, of that class in which a revolving corrugated roller is arranged above an endless apron in such a manner that theA articles to bewashed are drawn between the roller and apron. The inv'ention consists in the manner of hanging one of the rollers, around which the apron l passes, said roller being arranged nearly under the aforesaid corrugated roller. It is hung in dove-tail blocks which 'slide in corresponding grooves that are provided in the side boards of the ends-box. Spiral or other springs, the pressure of which can be regulated by means of nuts, press this roller against the corrugated roller, and the articles to be washed are, when placed upon the apron, brought between the two vrollers and worked between them until cleaned. The lower roller yields to allow the articles to be washed to pass between the4 rollers, and by the nuts the pressure is adjusted, in accordance with the nature of the article to be washed. Theinvention also consists in the device for operating the machine; said device' consisting of 'a treadle, which is connected, by means of rods, withcranks formed on the axle of the corrugated roller, that by means of the treadle, the said corrugated roller` can be revolved: The roller over which thefendless apron passes, being, by means ofthe springs, pressedagainst the corrugatedl roller,"is thus also revolved, and the endlesshapron is vcarried around without using any gear-wheels or other connections, between the corrugated roller and the apron rollers. The' whole machine being operated by the treadle, both hands of lthe operator are freel to adjust the wash on the apron, and to remove the same and reinsert it, as may be required. e,

. A represents a s uds-box, of suitable construction, made of wood or other suitable material. 'Its bottom, d, is either wholly or partly inclined. It is supported by four, more or"`less, 1egs B B, which aresecured near the 'corners' of the box to the side boards b b of the same, as shown. C is a corrugated roller,lhnving its bearings in the side boards blo ofthe box '.A. It is made of wood, and covered with corrugated metal, as shown in fig. 1. Its bearings are near to the upper edge of the side boards, las shown. To one end of the roller C is attached a. ily-wheel, D, on the outside of thebox. On both ends ofv the "roller C are vcranks c c, of yequal vlength and posi` tion. To their ends are attached rods, d d, which connect theroller C with a treadle, E, that is arranged below the suda-box, between .the legs B, as shown. This treadle consists of two longitudinal bars e e, which are pivoted to the legs that are at the rear end of the box, saidbars being connectedat their outer ends by a tread-board, f, and neartheir centres by a cross-bar, g, the ends of which latter extend beyond the bars e to receive the lower ends of the connecting-rods d d, as is clearly shown inthe drawings. F is a smooth roller, having its bearings in dove-tail blobks h h, that slide in corresponding grooves z' z', the latter being provided in an inclined direction on the inside of the side boards b b of the box A, as is clearly shown in the drawings. The upper ends of the grooves z' are closed. jj are rods, which extend from the blocks rh, through the covers of the'grooves z', and which carry on their outer ends spiral or other springs K K. l Z'are nuts, which are fitted upon the rods j, to compress the springs K. The further thesenuts are screwed down the more will 4the springs press against them, and with the more pressure will the roller :F be brought against the roller C, below which it is arranged as shown. The'roller Fis covered with felt or other elastic material, and carries an endless apron, G, which passes also over another roller, H, as shown -in iig. 1. The roller H is fixed, unadjustable, between the side boards b b ofthe box, near tothe'front end of the same, as shown. The wash is placed upon the apron Gr, and is brought under the roller C, which is revolved in the direction of the arrow 1 in iig. 1. Thereby the apron is moved in the direction of the arrow 2.

What I claim as new, andI desire to secure by Letters'Pratent, is-

1. The corrugated roller C, inA combination with the roller F,apron G, dove-tail blocks h, springs K, an'd nuts Z, all made and operating substantially as and for the purpose herein shown and described.

2.- The above,'in combination with the treadle E, when the same is made as set forth.- l
